Overview

  • The MIT Media Lab study used EEG monitoring to show that ChatGPT-assisted essay writers displayed the lowest neural engagement compared to peers writing unaided or with Google search.
  • In follow-up tests, 83% of participants who used ChatGPT reported difficulty quoting or recalling their own essays, indicating weaker memory retention.
  • A 2024 Pew Research Center survey found that 26% of teens used ChatGPT for school assignments, doubling from 13% in 2023.
  • Some schools are introducing AI literacy modules while others plan to emphasize in-person exams and stricter citation rules to uphold academic integrity.
  • Researchers warn that overreliance on AI tools without structured guidelines may lead to diminished critical thinking, creativity and problem-solving skills.
